2021-12-14RISC-V: Added ld testcases for the medlow and medany code models.Nelson Chu20-0/+280
There are two linker scripts, code-model-01.ld and code-model-02.ld, which are corresponding to the two different memory layouts, * code-model-01.ld: the text section is in the 32-bit address range, but the data section is far away from the text section, which means the data section is over the 32-bit address range. * code-model-02.ld: the text section is over the 32-bit address range, but the data section is placed nearly zero address. We use the two linker scripts, to test the current medlow and medany behaviors of GNU ld, including the weak symbol references and the relaxations behaviors. Besides, these testcases also show the limits of the current medlow and medany code models, that is - we may get the truncated to fit errors when linking with the above two linker scripts. ld/ * testsuite/ld-riscv-elf/code-model-01.ld: New testcases to test the behaviors of the current medlow and medany code models. * testsuite/ld-riscv-elf/code-model-02.ld: Likewise. * testsuite/ld-riscv-elf/code-model-medany-01.d: Likewise. * testsuite/ld-riscv-elf/code-model-medany-02.d: Likewise. * testsuite/ld-riscv-elf/code-model-medany-weakref-01.d: Likewise. * testsuite/ld-riscv-elf/code-model-medany-weakref-02.d: Likewise. * testsuite/ld-riscv-elf/code-model-medlow-01.d: Likewise. * testsuite/ld-riscv-elf/code-model-medlow-02.d: Likewise. * testsuite/ld-riscv-elf/code-model-medlow-weakref-01.d: Likewise. * testsuite/ld-riscv-elf/code-model-medlow-weakref-02.d: Likewise. * testsuite/ld-riscv-elf/code-model-relax-medany-01.d: Likewise. * testsuite/ld-riscv-elf/code-model-relax-medany-02.d: Likewise. * testsuite/ld-riscv-elf/code-model-relax-medany-weakref-01.d: Likewise. * testsuite/ld-riscv-elf/code-model-relax-medany-weakref-02.d: Likewise. * testsuite/ld-riscv-elf/code-model-relax-medlow-01.d: Likewise. * testsuite/ld-riscv-elf/code-model-relax-medlow-02.d: Likewise. * testsuite/ld-riscv-elf/code-model-relax-medlow-weakref-01.d: Likewise. * testsuite/ld-riscv-elf/code-model-relax-medlow-weakref-02.d: Likewise. * testsuite/ld-riscv-elf/code-model.s: Likewise. * testsuite/ld-riscv-elf/ld-riscv-elf.exp: Updated.

2021-11-19RISC-V: Support STO_RISCV_VARIANT_CC and DT_RISCV_VARIANT_CC.Nelson Chu6-0/+347
This is the original discussion, https://github.com/riscv/riscv-elf-psabi-doc/pull/190 And here is the glibc part, https://sourceware.org/pipermail/libc-alpha/2021-August/129931.html For binutils part, we need to support a new direcitve: .variant_cc. The function symbol marked by .variant_cc means it need to be resolved directly without resolver for dynamic linker. We also add a new dynamic entry, STO_RISCV_VARIANT_CC, to indicate there are symbols with the special attribute in the dynamic symbol table of the object. I heard that llvm already have supported this in their mainline, so I think it's time to commit this. bfd/ * elfnn-riscv.c (riscv_elf_link_hash_table): Added variant_cc flag.

2021-11-15PowerPC64 @notoc in non-power10 codeAlan Modra1-0/+1
R_PPC64_REL24_P9NOTOC is a variant of R_PPC64_REL24_NOTOC for use on @notoc cals from non-power10 code in the rare case that using such a construct is useful. R_PPC64_REL24_P9NOTOC will be emitted by gas rather than R_PPC64_REL24_NOTOC when @notoc is used in a branch instruction if power10 instructions are not enabled at that point. The new relocation tells the linker to not use power10 instructions on any stub emitted for that branch, unless overridden by --power10-stubs=yes.

2021-10-25libctf, ld: handle nonrepresentable types betterNick Alcock3-0/+36
ctf_type_visit (used, among other things, by the type dumping code) was aborting when it saw a nonrepresentable type anywhere: even a single structure member with a nonrepresentable type caused an abort with ECTF_NONREPRESENTABLE. This is not useful behaviour, given that the abort comes from a type-resolution we are only doing in order to determine whether the type is a structure or union. We know nonrepresentable types can't be either, so handle that case and pass the nonrepresentable type down. (The added test verifies that the dumper now handles this case and prints nonrepresentable structure members as it already does nonrepresentable top-level types, rather than skipping the whole structure -- or, without the previous commit, skipping the whole types section.) ld/ChangeLog 2021-10-25 Nick Alcock <nick.alcock@oracle.com> * testsuite/ld-ctf/nonrepresentable-member.*: New test. libctf/ChangeLog 2021-10-25 Nick Alcock <nick.alcock@oracle.com> * ctf-types.c (ctf_type_rvisit): Handle nonrepresentable types.

2021-10-22RISC-V: Added ld testcase for pcgp relaxation.Lewis Revill5-2/+36
Consider the the pcgp-relax-02 testcase, .text .globl _start _start: .L1: auipc a0, %pcrel_hi(data_a) .L2: auipc a1, %pcrel_hi(data_b) addi a0, a0, %pcrel_lo(.L1) addi a1, a1, %pcrel_lo(.L2) .data .word 0x0 .globl data_a data_a: .word 0x1 .section .rodata .globl data_b data_b: .word 0x2 If the first auipc is deleted, but we are still building the pcgp table (connect the high and low pcrel relocations), then there is an aliasing issue that we need some way to disambiguate which of the two symbols we are targeting. Therefore, Palmer thought of a way to use R_RISCV_DELETE to split this into two phases, so we could resolve the addresses before creating the ambiguities. This patch just add the ld testcase for the above case, in case we have changed something but break this. ld/ * testsuite/ld-riscv-elf/ld-riscv-elf.exp: Renamed pcgp-relax to pcgp-relax-01, and added pcgp-relax-02. * testsuite/ld-riscv-elf/pcgp-relax-01.d: Renmaed from pcgp-relax. * testsuite/ld-riscv-elf/pcgp-relax-01.s: Likewise. * testsuite/ld-riscv-elf/pcgp-relax-02.d: New testcase. * testsuite/ld-riscv-elf/pcgp-relax-02.s: Likewise.
2021-10-22RISC-V: Don't separate pcgp relaxation to another relax pass.Lewis Revill7-38/+34
Commit abd20cb637008da9d32018b4b03973e119388a0a and ebdcad3fddf6ec21f6d4dcc702379a12718cf0c4 introduced additional complexity into the paths run by the RISC-V relaxation pass in order to resolve the issue of accurately keeping track of pcrel_hi and pcrel_lo pairs. The first commit split up relaxation of these relocs into a pass which occurred after other relaxations in order to prevent the situation where bytes were deleted in between a pcrel_lo/pcrel_hi pair, inhibiting our ability to find the corresponding pcrel_hi relocation from the address attached to the pcrel_lo. Since the relaxation was split into two passes the 'again' parameter could not be used to perform the entire relaxation process again and so the second commit added a way to restart ldelf_map_segments, thus starting the whole process again. Unfortunately this process could not account for the fact that we were not finished with the relaxation process so in some cases - such as the case where code would not fit in a memory region before the R_RISCV_ALIGN relocation was relaxed - sanity checks in generic code would fail. This patch fixes all three of these concerns by reverting back to a system of having only one target relax pass but updating entries in the table of pcrel_hi/pcrel_lo relocs every time any bytes are deleted. Thus we can keep track of the pairs accurately, and we can use the 'again' parameter to restart the entire target relax pass, behaving in the way that generic code expects. Unfortunately we must still have an additional pass to delay deleting AUIPC bytes to avoid ambiguity between pcrel_hi relocs stored in the table after deletion. This pass can only be run once so we may potentially miss out on relaxation opportunities but this is likely to be rare. https://sourceware.org/bugzilla/show_bug.cgi?id=28410 bfd/ * elfnn-riscv.c (riscv_elf_link_hash_table): Removed restart_relax.

2021-09-03CC_FOR_TARGET et alAlan Modra31-321/+332
The top level Makefile, the ld Makefile and others, define CC_FOR_TARGET to be a compiler for the binutils target machine. This is the compiler that should be used for almost all tests with C source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS too. This was all supposed to work with the testsuite .exp files using CC for the target compiler, and CC_FOR_HOST for the host compiler, with the makefiles passing CC=$CC_FOR_TARGET and CC_FOR_HOST=$CC to the runtest invocation. One exception to the rule of using CC_FOR_TARGET is the native-only ld bootstrap test, which uses the newly built ld to link a copy of itself. Since the files being linked were created with the host compiler, the boostrap test should use CC and CFLAGS, in case some host compiler option provides needed libraries automatically. However, bootstrap.exp used CC where it should have used CC_FOR_HOST. I set about fixing that problem, then decided that playing games in the makefiles with CC was a bad idea. Not only is it confusing, but other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp. So this patch gets rid of the makefile variable renaming and changes all the .exp files to use the correct _FOR_TARGET variables. CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will correct bootstrap.exp to use CFLAGS, and a number of other things I noticed. binutils/ * testsuite/lib/binutils-common.exp (run_dump_test): Use CC_FOR_TARGET and CFLAGS_FOR_TARGET rather than CC and CFLAGS. ld/ * Makefile.am (check-DEJAGNU): Don't set CC to CC_FOR_TARGET and similar.
